BRUNO G. W. WOLFE AND WILHELM C. F. WOLFF, OF DEARBORN, MICHIGAN VENTILATHTG ARRANGEMENT FOR AUTOMOBILE HOODS Application filed April 8,

rangement wherein the parts are relatively so arranged that the side of the hood maybe raised without the interference of any of the cooperating parts, or the necessity of having to first uneou le them. I

vide means b which the shutters in the hood are automatically moved to closed position as the hood side is raised.

With these and other objects and advantages in view which will hereinafter become apparent, the invention is now; more :Eully described with the aid of the accompanying drawings, in which: I Figure 1 illustrates a side elevation of a portion of an automob1le to whichthe invention is applied. Figures 2 and 3 are enlarged sections on the lines 22 and 3-3 of Figure 1. Figure 4 'is an enlarged sectional detail showing a shutter inopen position. I Figure 5 is an enlarged view of the operating rod showing a means for holding the latter in adjusted position. v Figure 6 is an enlarged section on the line 6-6ofFigure1. I I I Referring to the drawings, 1 designates a: portion of an automobile frame and 1a a portion of a front fender, 2 is a dash board, 3 an instrument board, and 4 a hood. Each side of the latter has a plurality of aligned ventilating apertures 5 formed therethrough, and

6 denotes shutters pivotally mounted on the hood sides so that they may close the aper- 5 tures 5. Since the construction and arrangement of parts for actuating the shutters isv the same on both sides of the hood and vehicle, I will describe my structure with reference toone side only.

00 Horizontally slidable on the inner side of A further 0 ject of the invention is to pro-'1 J in which they-are arranged 1 193-1.- Serial No. 528,524.

the hood 4, and preferably intermediately. of

the height of the apertures 5 is a memberj7. Extending inwardlyfroni each shutter 6 and p votally connected thereto is an arm 8 the,

' inner extremity vof which is pivotally connected tothemember so that when the lat- .ter is moved longitudinally the shutters are turned about theiraxes and opened or closed: One extremity ofa spring 9 is secured tothe member 7 and its opposite extremity .is ise- "cured to the innersidefof the hood 4. This spring tends to move the said member forwardly so that thel shutters G are returned to their closed-position. Onthe inner'side of to the member f that forward movement of the lower extremlty of the said lever movesthe member '7 rearwardlyagainst the tension of thespring- .9 and-,causes-the shutters'6 to open; .The lower extremity of the-said lever preferably extends below the side of the hood 4.. The 'action offthe spring 9 thus. tends to hold the lever 10. in the. position shown in Figure 1. I

T0 the inner upturned. extremity of the front fender la a guidell is secured 'throu h which an element 12 islongitudinally slidab e.

Extending forwardly through the instrument 8o board 3 and dash 2 is an operating rod 14 to the front extremityof which the upper extremity of a connecting link 15 is pivotally fastened. This link, intermediately of its length, is pivotally supported by a bracket 16 mountedon the front of the dash 2, and at its lower-extremity is pivotally connected to the rear extremity of the e1ement12. The latter is bifurcated at its front extremity as shown at 12a to receive the lower end ofthe lever 9' between its bifurcations.

One extremity of a spring 17 is secured to any suitable port-ionof the vehicle such as the underside ofthe floor boards indicated at 17a. The opposite end of the spring 17 is secured to the lower extremity of the lever 15 thereby tending to move the latter andthe eleme t 12 into theposition shown in -Figure-1.'-j'

In order to hold the .operat' g'rod 14 at any desired setting araek 18 is provided there- I I I I I the hood 4 a lever 10 ,5 1s plvotally mounted lntermediately of its length. Its upper'extremityisso-connected on which coacts with a corresponding rack 19 supported by a spring 20 from the instrument board 3. This, or any preferred equivalent structure, is employed for preventing accidental movement of the operating rod 14 and the other parts with which it cooperates and which are subjected to the tension of the springs 9 and 17.

From the foregoing it will be readily seen that when the rod 14: is moved rearwardly the element 12 is moved forwardly. Then the base of the bifurcated portion 12a moves the lower extremity of the lever 10 forward, thereby causing the member 7 to move rearwardly so that the shutters 6 are opened. By movement of the operating rod 14 in the opposite dircction-na1nely forwardly-the element 12 is moved rearwardly; when this occurs the spring 9 moves the member 7 forwardly thereby closing the shutters 6 and causing the lower extremity of the lever 10 to travel rearwardly substantially in engagement with the base of the bifurcated portion 12a of the element 12. It will also be observed that if the shutters 6 are open and the side of the hood raised the shutters are closed by the action of the spring 9 as soon as the hood is lifted sufficiently for the lever 10 to become disengaged from the bifurcation 12a. Moreover should the operating rod 14 be in rearward position when the hood is raised it is merely necessary to return'it to its forward position before again lowerin the hood, then the lever 10 will reengage the ifurcation 12a.

\Vhile the mechanism will operate successfully without the spring 17 we prefer that it v be utilized as it eliminates noise which might otherwise occur when the vehicle is in motion.

- While in the foregoing the preferred embodiment of the invention has been described and shown, it is understood that the construction described is susceptible to such all terations and modifications as fall within the scope of the appended claims.

What we claim is:

1. An arrangement of the character described comprising an apertured hood, shutters, a member movable on said hood by the movement of which said shutters open and close said hood apertures, a lever pivoted on said hood and'connected to said member, and spring means tending to move said shutters to closed position relative to said hood apertures, in combination with a frame, an element movable longitudinally of said frame means on said element for engaging and moving said lever when said element is moved in one direction, and means for moving said element.

2. An arrangement. of the character describedcomprising an apertured hood shutters, a mem er movable on said hood by the movement of which said shutters open and close the hood apertures, a lever pivoted on said hood and connected to said member, and

movement of which said shutters open and v close the hood apertures, a lever pivoted on said hood and connected to said member, and spring means tending to hold said shutters in closed position relative to said apertures, in combination with a frame, an -element bifurcated at one extremity slidable,on said frame, said bifurcated extremity engaging said lever and moving it in one direction when said element is moved in one direction, and means for moving said element.

4. In an arrangement of the character described, the combination ofa frame, a body mounted thereon, an operating rod slidable in said body, an element longitudinally movable on said frame, means connecting said rod with said element, a hood having apertures therein, shutters adapted to close said' apertures, said hood being substantially centrally and longitudinally hinged and mounted over a portion of said frame so that either side thereof may be raised, a member slidable on said hood by movement of which said shutters open and close said apertures, a lever pivoted on said hood and connected to said member," said lever being adapted to be engaged by one extremity of said element so that movement of the latter in one direction opens said shutters, said lever becoming disengaged from said element when the hood side is raised about its hinges, and spring means tending to hold said lever in engagement with said element when the hood side BRUNO G.
